Application filed December 6, 1922. Serial Nb. 605,157.

To all whom it may concern:

Be it known that I, FENTQN R. BRYDLE, a citizen of the United States, residin at Jamaica, in the county of Queens and i tate of New York, have invented certain new and useful Improvements in Interlocking Shingles, of which the following is a specification.

This invention relates to I composltion shingles of the interlocking type.

Roofing or other shingles formed of tibrous material impregnated with asphaltum and having a rectangular formation adapted to be laid in a diagonal or oblique position are well known. The lowermost corners of such shingles have been utilized as anchoring tabs, which in some cases have been turned back on themselves underneath the main body of the attached shingle and provided with laterally projecting wire elements for anchoring engagement underneath the edges of adjacent shingles. In other cases the shingles have been provided with inwardly extending slots in the lateral. margins thereof at the base of the tabs, the slots serving to receive, the edges of previously laid shingles beneath which the lateral corner portions of the tab extend while the main body portion of the tab projects downwardly as a projection or extension of the shingle itself. Tabs of either described type are open to the objection that they are easily torn from their points of attachment to the main body of the shingle under thestress of handling in the act of sliding the tabs into anchoring position in the laying operation, or under the strain of wind action after the shingles have been laid in position.

An object of the present invention is to provide a shingle which will be free from the objections referred to and which will resist rupturing strains and be held securely in fiat position in any condition which is likely to beencountered during the operation of laying the shingles or subsequently thereto.

My invention includes the use of metal or other reinforcing members carried by underturned corner tabs forming part of the I shingles and adapted to occupy anchoring Other features of the invention will be hereinafter described.

In the drawings, in which several embodiments of the invention have been selected for illustration,

Figure 1 is a face view of a number of shingles constructed in accordance with the invention and showing their relation to each other when laid in permanent position.

Figure 2 is a plan view of the underside of a corner portion of a shingle constructed in accordance with the invention before the anchoring tab is turned back on itself.

Figure 3 is a plan view similar to Figure 2 showing the tab folded for anchoring relation with an underlying shingle.-

Figure 4: is a plan View similar to Figure 2 showing a modified form of reinforcin%clip.

igure 5 is a plan View similar to Figure 2 showing still another form of reinforcing clip. Figure 6 is a plan view similar to Figure 2 showing a modified form of anchoring{tab and reinforcing means.

eferring to the drawings for a more detailed description of the invention, shingles 5 are shown which are preferably formed of any suitable water-proof composition such as asphaltum-treated felt or other fibrous material. The shingles are rectangular in form and are intended to be laid diagonally'or obliquely as is indicated in Figure 1 of the drawing. In order to anchor the shingles in position the lowermostcorner is'fo'rmed into a tab member 6 which is turned under and back on itself for positioning beneath the flanking edges of the adjacent previously laid shingles as at 7 and 8 in Figure 1 of the drawing.

In order to provide a more secure anchorage of the overlying shingles than has been heretofore attained, I make use of metal reinforcing members 10, 10 10 and .10 affixed to the tabs and bent back on them selves to engage both the upper and lower surfaces of those portions of the anchoring shingles underneath which the tabs of the overlying shingles are pushed to anchoring position in the operation of laying the shingles. llhe reinforcing member preferably extends into the extreme apex portion of each tab to facilitate the operation of pushing the tab to anchoring position and in a preferred form of the invention, as in Figure 2, extends to the lateral margins of the tab as well. While the reinforcing member, which may be formed of relatively rigid rust-proof sheet metal, thus extends to the margin or edge of the tab it does not extend beyond the edge of the tab in overhanging relation thereto, so that the tab and its reinforcing member mutually support each other to most effectively resist pulls and strains tending to unseat the tabs from anchoring position.

In order to obtain the desired seating of the lateral portions of the tab beneath the previously-laid shingles I may provide inwardly extending slits 11 at the extremities of the line of bend 12 of the tab and its junction with the main body of the shingle. I contemplate also the lateral enlargement of the corner tab portion as at 13 in Figure 6 of the drawing, this also providing for the seating of the lateral portions of the tab beneath previously-laid shingles when'the overlying shingle is laid in place and rendering the slits in the edges of theshingle unnecessary. I

I may employ reinforcing members of difi'erent formations. In Figure 42 of the drawing a reinforcing member 10 is shown in the form of a strip of metal extending longitudinally of the vertical axis of the tab and shingle. In Figure 5 the reinforcing member 10 takes the form of an inverted V-shaped strip. In each form the line of bend of the tab'falls between the ends of the reinforcing member so that the reinforcing member is folded into a U-shaped formation to provide a pair of arms or extensions between which portions of previously-laid shingles extend with the arms in engagement with both the upper and lower surfaces thereof.

In order to attach the reinforcing members to the tab a simple V-shapedtongue 14 is produced in the body of the reinforcing member by any suitable forming operation, the tongue being forced into the tab as indinaiaaoo cated. In addition to the mechanical cooperation of the tongue with the tab the 1mpregnant which is employed to waterproof the shingles may have adhesive properties which will cause the engaged surfaces of the shingle and reinforcing or anchoring memher to adhere to each other.

With the construction described the extended portion of the exposed part of each shingle is securely anchored in a flat position against the upper surfaces of adjacent previously-laid shingles, the reinforced tab members being pushed upwardly beneath the anchoring shingles in the angle formed by the adjacent corners of two shingles. The metal reinforcing clip prevents the tearing of the tab from the shingle in the operation of pushing the anchoring tab to position and also overcomes the destructive action of wind in its tendency to unseat the shingles that are not securely anchored in position.

What I claim is 1. In a shingle of the flexible type, an underturned tab formed on a margin of the shingle for anchoring engagement with a previously laid shingle, and a reinforcing member carried by the tab, said reinforcing member being formed to engage portions of both the upper and lower surfaces of the previously-laid shingle.

2. In a shingle of the flexible type, an underturned corner tab formed on the shingle for anchoring relation with a previouslylaid shingle, and a sheet metal reinforcing member attached to the upper surface of the tab for engagement with the lower surface of the anchoring shingle.

3. In a-shingle of theinterlocking type, an underturned anchoring tab formed on a margin of the shingle, said anchoring tab being formed with a reinforcing. member coextensive with the length of the tab.

4. In a shingle of the flexible type, an underturned anchoring tab formed on a margin of the shingle and adapted to occupy a position beneath a previously-laid shin 1e, said anchoring tab being provided with a llMD reinforcing member formed to engage both:

the upper and lower surfaces of t e underlying shingle.

5. In a shingle of the flexible type, an underturned corner tab formed ,on the shingle for anchoring relation with a previously-laid shingle, and a sheet metal reinforcing member attached to the upper for receiving and holding a portion of the and a sheet metal reinforcing member atunderlying shingle between the arms of the tached to the up er surface of the tab s aid member. reinforcing mem er having a U-shaped for- 7.
